Jean-Louis Gassée posits that Apple's reliance on Intel chips for Macs could soon be over:

[T]he advantages of ARM-based processors vs. x86 devices become even more compelling: lower cost, better power dissipation, natural integration with the rest of the machine. For years, Intel has argued that its superior semiconductor design and manufacturing technology would eventually overcome the complexity downsides of the x86 architecture. But that “eventually” is getting a bit stale. Other than a few showcase design wins that have never amounted to much in the real world, x86 devices continue to lose to ARM-derived SoC (System On a Chip) designs.
I wouldn't be surprised if someday in the not-too-distant future, Phil Schiller reveals that Apple's been secretly running Macs on the company's A-series chips for a long time now --- much in the same way Steve Jobs announced the PowerPC to Intel transition in 2005.
